Here is an interesting one, this is sort of related..


You've all played Super Mario Bros 2 on the Nes? well it's not technically the original Super Mario Bros 2.

After the success of the first game, a follow up was released in Japan - Super Mario Bros 2 which looked and played just like the original. However the creators thought the game would be too difficult for US and European gamers, so they went to work on something different. The Japanese Famicom had a game called 'Doki Doki Panic' which was becoming popular, so they released it in the US and Europe under the title 'Super Mario Bros 2' (the Japanese refer to it as 'Mario USA').


They replaced the original Doki Doki Panic sprites, with that of Mario related characters, as well adding a few extras (Mario theme, mushrooms and so on).


So in a way we were cheated out of the proper Mario 2, that is until it finally made it's way to US and European consoles on the Super Nintendo compilation 'Super Mario All stars' only this time under the name 'Super Mario Bros: The Lost Levels'.


So two Super Mario Bros 2, but in fact different games, and the Japanese were not wrong, the game is very hard indeed.


A lot of this is off the top of my head, so please forgive if there are any inaccuracies.
